Answer:
The time that the rocket will hit the ground will be:
Step-by-step explanation:
Given the expression

Here:
- x represents the time in seconds
- y represents the height of the rocket
We know that when the rocket will hit the ground, the height will get y = 0
i.e.

solving for x to determine the time that the rocket takes when it will hit the ground.
so

subtract 110 from both sides


Divide both sides by -16







solving


x = 17.40 seconds
also solving


x = -0.40 seconds
As time can not be negative.
Thus, the value of x = 17.40 seconds
Therefore, the time that the rocket will hit the ground will be:
Answer:
12.67 minutes
Step-by-step explanation:
Time taken is given by distance divided by speed
Given distance of 228, 000, 000 km and speed of light as 300, 000 km/s then time will be
Time=228, 000, 000/300, 000=760 seconds
Conversion
60 seconds make up 1 minute
760 seconds will be 760/60
Time=760/60=12.666666666666
Rounded off, this is 12.67 minutes
